Pedra Furada da Serra da Ribeirinha Loop

This medium circular walk on Terceira covers about 6.6 km / 4.1 miles with roughly 300 m / 984 ft of climbing, usually taking around 2 hours 30 minutes. The route starts beside the Ribeirinha Ethnographic Center in the parish of Ribeirinha, at approximately Canada do Capitão-Mor, Ribeirinha, Angra do Heroísmo, Terceira, Azores, using the published trailhead coordinates of 38.663206, -27.177831. The path ranges from about 193 m to 404 m above sea level, or roughly 633 ft to 1,325 ft, so although the distance is modest, the steady ascent and uneven rural surfaces justify the medium rating.

The character of the walk is shaped by water, stone, pastureland, and scattered settlement. Early on, the route threads through the parish streets and passes traditional water points including A Fonte and Poça de Adão, reminders of how important springs and fountains were to daily life in this part of the island. From there, the trail climbs into the Serra da Ribeirinha through an agricultural landscape with dry-stone walls, grazing land, and open views over the Bay of Angra do Heroísmo and Terceira’s south coast. On clear days, the higher sections also frame major volcanic landforms including Cinco Picos, Guilherme Moniz, and Serra de Santa Bárbara. (turismo.azores.gov.pt)

What to expect on the route

The first 1 to 2 km / 0.6 to 1.2 miles are the gentlest, following village lanes and access tracks where the gradient is manageable and footing is generally straightforward. After that, the route becomes more distinctly rural, with a more sustained climb through farm tracks and hillside paths. Expect a mix of paved stretches, dirt lanes, and rougher ground near the rock features. In wet weather, these surfaces can become slick, especially where mud, grass, or worn stone overlap, so sturdy footwear with good grip is important. (acores9.com)

The trail’s main interpretive theme is its series of seven rock groups, which include unusual formations, basins or hollows known as pias, and cut-like markings in the stone. The best-known feature is the Pedra Furada itself, a perforated or window-like rock formation that gives the route its name. These features are part of what makes the walk more than a simple countryside loop: it is a route where geology, local interpretation, and cultural memory all overlap. Some of the markings have inspired debate over whether they are entirely natural or partly shaped by people, so this is a hike that rewards slow observation rather than rushing from viewpoint to viewpoint.

Farther along, the route reaches an old World War II lookout post, adding a 20th-century historical layer to a landscape otherwise dominated by volcanic terrain and rural land use. Several viewpoints are scattered along the return, and these help break up the descent with broad coastal and upland panoramas. (turismo.azores.gov.pt)

Nature, terrain, and wildlife

Most of the scenery is agricultural rather than deeply forested, but that does not make it monotonous. The appeal lies in the contrast between open pasture, water sources, rocky outcrops, and the broad volcanic backdrop. The Serra da Ribeirinha forms part of the southwestern slope of the Cinco Picos volcano, whose caldera is described by the Azores tourism authority as the largest volcanic caldera in the Azores. That volcanic setting is central to the feel of the walk, even when you are moving through human-shaped terrain. (turismo.azores.gov.pt)

Wildlife is likely to be subtle rather than dramatic. Expect common rural birdlife, insects around wetter spots, and domestic animals in grazing areas. Because the route crosses private land and pasture, cattle are one of the main things hikers need to be aware of. Give animals plenty of space, move calmly, and leave every gate exactly as you find it. The official trail information specifically warns hikers to pay attention around cattle and other domestic animals and to keep gates closed.
